Smith has always had a pretty good sense of spacing. He was rarely in a position to get hit at BC and that's starting to translate at the NHL level. He's also getting better at that on the breakout. For the last couple games, he's been reading the rim outs well and getting into position on the boards early to get the puck out of the zone.
According to NHL Edge data, he has one of the harder average shots in the NHL but I think a lot of that is this sense of spacing since he always has so much time to load up when he takes his shot. Could stand to make quicker shots but this is fun too.
